These programs place advertisements on a Web-surfer's screen in exchange for a small hourly rate paid to the viewer. When people sign up through a banner or link on your site, you will receive a recurring commission based on the number of hours they use the program. When they recruit others, you will also receive commissions for the direct "descendants" to a certain number of levels (e.g. five.)

All of these programs require some usage by you personally. This may be as little as one hour per year for some, but others may base your "downline" commission on your own accumulated hours.
